Proctoscopy, or rectoscopy, is a common medical procedure in which an instrument called a proctoscope (also known as a rectoscope, although the latter may be a bit longer) is used to examine the anal cavity, rectum, or sigmoid colon. A proctoscope is a short, straight, rigid, hollow metal tube, and usually has a small light bulb mounted at the end.
Rectal administration (colloquially known as boofing or plugging) uses the rectum as a route of administration for medication and other fluids, which are absorbed by the rectum's blood vessels, [Note 1] and flow into the body's circulatory system, which distributes the drug to the body's organs and bodily systems.
A Cochrane review updated in 2016 found strong evidence that chromoscopy enhances the detection of cancerous tumors in the colon and rectum. [62] In most experienced hands, the endoscope is advanced to the junction of where the colon and small bowel join up in under 10 minutes in 95% of cases. Due to tight turns and redundancy in areas of the ...
Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. [1] The field is also known as proctology, but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular.
Rectal bulb syringe to administer smaller enemas. An enema, also known as a clyster, is the rectal administration of a fluid by injection into the lower bowel via the anus. [1] The word enema can also refer to the liquid injected, [2] [3] as well as to a device for administering such an injection. [4]
The practice of rectal exams without prior consent by medical students has been an area of concern. [32] In 2024, the US Department of Health and Human Services banned rectal examination (and pelvic and breast exams) without written informed consent, when such exams are undertaken by medical students, nurse practitioners, or physician ...
Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum. The term barium enema usually refers to a lower gastrointestinal series, although enteroclysis (an upper gastrointestinal series) is often called a small bowel barium enema.
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. [2] However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.
